Hi all just a few questions about the xenons you get as standard on the e92

So I understand they are auto levelling - mine seem to do this while driving too, going over speed bumps etc you can see the lights trying to level out. Is this right?

Now when I got the car the lights were aimed really low so I used the adjustment screw on the top of the light cluster to bring them up. I had to adjust the screw all the way to the end to get the light spread high enough to see properly (while obviously ensuring the aim was not too high to blind other road users) but even with them set at the highest level they still seem to be aiming too low? Maybe the auto levelling is bringing them down.. By too much?

I had a 2007 335d and the lights on that were superb, on my 2011 I agree the lights on dip seem to be set lower and consequently not as good as the 2007. I wonder if bmw set them like this so as not to dazzle oncoming drivers?

Car had her mot today, on collection the mechanic pointed me to the advisory that the auto-leveling arm on the NSF was not fitted properly or damaged.

I've just jacked the car up and had a look at the auto-leveling arm, the clip holding it onto the wishbone wasn't 'snapped' shut, probably causing the arm to ride up and down the wishbone and getting the sensor confused.

I had a play and the lights do adjust as you move the arm. I put it back into position and snapped the clip shut.

Here is the arm

As I've mentioned before, I had to wind the adjustment screw all the way in to get the light horizon high enough to see. If your lights still don't point high enough then you can loosen off the two screws that hold the light cluster into the car, and manoeuvre the light cluster down at the back so the lights point higher. Put your lights on while you do this and you will see the little movements can give you that extra few degrees of tilt

Question , does the autolevelling only occur when you start the car ( down to reset then up) ?

or !

Are they constantly 'levelling' .. for example whipping down a straight road at a good old pace , then sudden braking , nose dives .. at this point does the auto-level compensate for this and adjust up.

May sound a stupid question from someone with an e92 but my system is static because I have a known faulty sensor on the front
